[libc++][lldb-dap][test] Fix CI for bootstrapping-build (#141543)

#140107 changed the default argument of `disableASLR` of related
functions from `False` to `True`. libc++ CI has been stably failing for
`TestDAP_subtleFrames.py` (in bootstrapping-build) since then. The error
message "personality set failed: Operation not permitted" seems related
to ASLR.

This PR attempts to fix the CI failure by changing the default value of
`disableASLR` in `dap_server.py` to `False`.
